A screenshot of the Light Pollution Simulator: the default screen.

The most distant protocluster discovered by the Subaru Telescope. The blue shading shows the calculated extent of the protocluster, and the bluer color indicates higher density of galaxies in the protocluster. The red objects in zoom-in figures are the 12 galaxies found in it. This figure shows a square field-of-view 24 arcminutes along each side (corresponding to 198 million light-years along each side at a distance of 13.0 billion light-years). Each zoom-in figure is 16 arcseconds along each side (corresponding to 2.2 million light-years).

Hubble Tracks a Galaxy on the Move

NASA’s Solar Dynamics Observatory captured this view of a solar eruption on April 21, 2015.

This illustration shows a tidal disruption, which occurs when a passing star gets too close to a black hole and is torn apart into a stream of gas. Some of the gas eventually settles into a structure around the black hole called an accretion disk.

Glowing Solar Cell

Seen nearly edgewise, the turbulent disk of gas churning around a black hole takes on a crazy double-humped appearance. The black hole’s extreme gravity alters the paths of light coming from different parts of the disk, producing the warped image.

Found - Three Black Holes On Collision Course

A prototype of the transforming robot Shapeshifter is tested in the robotics yard at NASA's Jet Propulsion Laboratory. Shapeshifter is made of smaller robots that can morph into rolling spheres, flying drones, swimming submersibles, and more.
